I must say that it is interesting to see the differences between your usual painting techniques and this more … please accept my apologies for any lack of the proper technical term, I fear I am an amateur admirer and not a professional critic … well your habitual style seems to be more oils, while this looks more inked! (I very much admire an artist willing to leave their comfort zone every so often).

(The fact that this is a wonderfully seductive image also enhances my appreciation).
